Engine question?????

OK, say ur stopped at the red light waitting for the light to change! The light changes and u floor it, the car responds properly but just after that good response the engine kinda like bogs down than picks up power again quickly. Is this common on 7's? IDK....
Maybe has something to do with traction control or maybe DCT.. ANY help would be gladly appreciated. Many thx in advance.

Don't have this issue, are you flooring it? Try better gas, I do notice difference between chevron and other brands. If that does not help second thing I would try before going to mech is fuel system treatment.

lol that aint fuel,.... if you floor it from a stop then its the traction control...... it will limit the engine.... turn on dts, or turn DSC off then try it.. if you hav same results with DSC off then its a different problem

Thanks for the reply 7rage. That's exactly how the engine does. Like when I take off something limits the engine for a slight second than thrust .
